- Abstract
- In this paper, we exploit the concept of array pattern synthesis to design cluster beamformers with partial channel state information for non-orthogonal multiple access downlink multiuser transmission in millimeter wave channels. Using the information on angle-of-departure region for each user, we formulate an array pattern nulling problem to design each cluster beamformer for minimizing inter-cluster interferences, which is solved by using semidefinite programing. Further, we exploit linear programing to solve a power allocation problem for each user in the cluster to achieve a target signal-to-interference-and-noise ratio. Numerical results are presented to verify the validity of the proposed schemes. © 1967-2012 IEEE.
